Question about NZBdrone moving files? Parallel?

In a nut shell I wanted to know does NZB Drone move multiple files at once? If so, is there way to change that so it does it one by one.
The reason I ask is because I use Google Drive to store some TV Shows but I use WebDrive to mount Google Drive as a network drive (the files are uploaded to Google Drive, not synced, ie. no local storage used). When I download multiple TV Shows and NZB Drone tries to move them all it seems to crash WebDrive. The first 1 or 2 get uploaded fine, then the rest of the just disappear and NZB Drone shows them as failed.
I’m assuming NZB Drone think it has initiated the move, WebDrive tries to upload them, it crashes, corrupting the files, NZB Drone reports them as failed?

it’s done sequentially. If the filesystem is causing the issue, there isn’t anything we can do about it.
